Nutritional Yeast Flakes
Nutritional yeast (informally called nooch) is a deactivated (i.e., dead) yeast, often a strain of ''Saccharomyces cerevisiae'', that is sold commercially as a food product. It is sold in the form of yellow flakes, granules, or powder, and may be found in the bulk aisle of natural food stores. It is used in vegan and vegetarian cooking as an ingredient in recipes or as a condiment. It is a source of some B-complex vitamins and contains trace amounts of several other vitamins and minerals. It is often fortified with vitamin B12. Nutritional yeast has a strong flavor described as nutty or cheesy for use as a cheese substitute. It may be used in preparation of mashed potatoes or tofu. Nutritional yeast is a whole-cell inactive yeast that contains both soluble and insoluble parts, which is different from yeast extract. Yeast extract is made by centrifuging inactive nutritional yeast and concentrating the water-soluble yeast cell proteins which are rich in glutamic acid, nucleo ...

Nucleotides
Nucleotides are Organic compound, organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all Life, life-forms on Earth. Nucleotides are obtained in the diet and are also synthesized from common Nutrient, nutrients by the liver. Nucleotides are composed of three subunit molecules: a nucleobase, a pentose, five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine, and thymine; in RNA, uracil is used in place of thymine. Nucleotides also play a central role in metabolism at a fundamental, cellular level. They provide chemical energy—in the form of the nucleoside triphosphates, adenosine triphosphate (ATP), guanosine triphosphate (GTP), cytidine triphosphate (CTP), and uridine triph ...

Vegan Cheese
Vegan cheese is a category of non-dairy, plant-based cheese alternative. Vegan cheeses range from soft fresh cheeses to aged and cultured hard grateable cheeses like plant-based Parmesan. The defining characteristic of vegan cheese is the exclusion of all animal products. Vegan cheese can be made with components derived from vegetables, such as proteins, fats and plant milks. It also can be made from seeds, such as sesame, sunflower, nuts (cashew, pine nut, peanuts, almond) and soybeans; other ingredients are coconut oil, nutritional yeast, tapioca, rice, potatoes and spices. History Fermented tofu (''furu'') has been documented in China since the late 16th century. The savory product is used as a condiment to accompany rice or porridge. Western sources from the 19th to 21st centuries repeatedly draw a comparison between ''furu'' and cheese, going as far as calling it a "nondairy/vegan cheese". Later homemade vegan cheeses were made from soy flour, margarine, and yeast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marmite
Marmite ( ) is a British savoury food spread based on yeast extract, invented by the German scientist Justus von Liebig. It is made from by-products of beer brewing ( lees) and is produced by the British company Unilever. Marmite is a vegan source of B vitamins, including supplemental vitamin B12. A traditional method of use is to spread it very thinly on buttered toast. Marmite is a sticky, dark brown paste with a distinctive, salty, powerful flavour and heady aroma. This distinctive taste is represented in the marketing slogan: "Love it or hate it." Such is its prominence in British popular culture that Marmite is often used as a metaphor for something that is an acquired taste or polarises opinion. Marmite is commonly used as a flavouring, as it is particularly rich in umami due to its very high levels of glutamate (1960 mg/100 g). The image on the jar shows a ''marmite'' (), a French term for a large, covered earthenware or metal cooking pot. Marmite was o ...

Cyanocobalamin
Cyanocobalamin is a form of Vitamin B12, vitamin used to treat and prevent vitamin B12 deficiency, vitamin deficiency except in the presence of cyanide toxicity. The deficiency may occur in pernicious anemia, following gastrectomy, surgical removal of the stomach, with fish tapeworm, or due to bowel cancer. It is used by mouth, by injection into a muscle, or as a nasal spray. Cyanocobalamin is generally well tolerated. Minor side effects may include diarrhea, nausea, upset stomach, and itchiness. Serious side effects may include anaphylaxis, and low blood potassium resulting in heart failure. Use is not recommended in those who are allergic to cobalt or have Leber's disease. No overdosage or toxicity has been reported. It is less preferred than hydroxocobalamin for treating vitamin deficiency because it has a slightly lower bioavailability. Some studies have shown it to possess an antihypotensive effect. Vitamin is an essential nutrient meaning that it cannot be made by the ...

Mineral (nutrient)
In the context of nutrition, a mineral is a chemical element. Some "minerals" are essential for life, but most are not. ''Minerals'' are one of the four groups of essential nutrients; the others are vitamins, essential fatty acids, and essential amino acids. The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium. The remaining minerals are called " trace elements". The generally accepted trace elements are iron, chlorine, cobalt, copper, zinc, manganese, molybdenum, iodine, selenium, and bromine; there is some evidence that there may be more. The four organogenic elements, namely carbon, hydrogen, oxygen, and nitrogen ( CHON), that comprise roughly 96% of the human body by weight, are usually not considered as minerals (nutrient). In fact, in nutrition, the term "mineral" refers more generally to all the other functional and structural elements found in living organisms. Plants obtain minerals from soil. Animals ingest plants, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daily Value
In the U.S. and Canada, the Reference Daily Intake (RDI) is used in nutrition labeling on food and dietary supplement products to indicate the daily intake level of a nutrient that is considered to be sufficient to meet the requirements of 97–98% of healthy individuals in every demographic in the United States. While developed for the US population, it has been adopted by Canada. The RDI is used to determine the Daily Value (DV) of foods, which is printed on nutrition facts labels (as %DV) in the United States and Canada, and is regulated by the Food and Drug Administration (FDA) and by Health Canada, respectively. The labels "high", "rich in", or "excellent source of" may be used for a food if it contains 20% or more of the DV. The labels "good source", "contains", or "provides" may be used on a food if it contains between 10% and 20% of the DV, and "low source" applies if the %DV is 5% or lower. The Recommended Dietary Allowances (RDAs) were a set of nutrition recommenda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B Vitamins
B vitamins are a class of water-soluble vitamins that play important roles in Cell (biology), cell metabolism and synthesis of red blood cells. They are a chemically diverse class of compounds. Dietary supplements containing all eight are referred to as a vitamin B complex. Individual B vitamins are referred to by B-number or by chemical name, such as B1 for thiamine, B2 for riboflavin, and B3 for niacin, while some are more commonly recognized by name than by number, such as pantothenic acid (B5), biotin (B7), and folate (B9). B vitamins are present in protein (nutrient), protein-rich foods, such as Fish as food, fish, poultry, meat, dairy products, and Eggs as food, eggs; they are also found in Leaf vegetable, leafy green vegetables, beans, and peas. food fortification, Fortified foods, such as breakfast cereals, baked products, and infant formulas, may contain B vitamins. Each B vitamin is either a cofactor (biochemistry), cofactor (generally a cofactor (biochemistry), coenzym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calorie
The calorie is a unit of energy that originated from the caloric theory of heat. The large calorie, food calorie, dietary calorie, kilocalorie, or kilogram calorie is defined as the amount of heat needed to raise the temperature of one liter of water by one degree Celsius (or one kelvin). The small calorie or gram calorie is defined as the amount of heat needed to cause the same increase in one milliliter of water. Thus, 1 large calorie is equal to 1,000 small calories. In nutrition and food science, the term ''calorie'' and the symbol ''cal'' may refer to the large unit or to the small unit in different regions of the world. It is generally used in publications and package labels to express the energy value of foods in per serving or per weight, recommended dietary caloric intake, metabolic rates, etc. Some authors recommend the spelling ''Calorie'' and the symbol ''Cal'' (both with a capital C) if the large calorie is meant, to avoid confusion; however, this convention ...

Protein (nutrient)
Proteins are essential nutrients for the human body. They are one of the constituents of Tissue (biology), body tissue and also serve as a Fuel, fuel source. As fuel, proteins have the same energy density as carbohydrates: 17 Joule, kJ (4 Calories, kcal) per gram. The defining characteristic of protein from a nutritional standpoint is its amino acid composition. Proteins are polymer chains made of amino acids linked by peptide bonds. During human digestion, proteins are broken down in the stomach into smaller polypeptide chains via hydrochloric acid and protease actions. This is crucial for the absorption (small intestine), absorption of the essential amino acids that cannot be biosynthesized by the body. There are nine essential amino acids that humans must obtain from their diet to prevent protein–energy malnutrition, protein-energy malnutrition and resulting death. They are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbohydrate
A carbohydrate () is a biomolecule composed of carbon (C), hydrogen (H), and oxygen (O) atoms. The typical hydrogen-to-oxygen atomic ratio is 2:1, analogous to that of water, and is represented by the empirical formula (where ''m'' and ''n'' may differ). This formula does not imply direct covalent bonding between hydrogen and oxygen atoms; for example, in , hydrogen is covalently bonded to carbon, not oxygen. While the 2:1 hydrogen-to-oxygen ratio is characteristic of many carbohydrates, exceptions exist. For instance, uronic acids and deoxy-sugars like fucose deviate from this precise stoichiometric definition. Conversely, some compounds conforming to this definition, such as formaldehyde and acetic acid, are not classified as carbohydrates. The term is predominantly used in biochemistry, functioning as a synonym for saccharide (), a group that includes sugars, starch, and cellulose. The saccharides are divided into four chemical groups: monosaccharides, disaccharides, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Food Fortification
Food fortification is the addition of micronutrients (essential trace elements and vitamins) to food products. Food enrichment specifically means adding back nutrients lost during food processing, while fortification includes adding nutrients not naturally present.World Health Organization and Food and Agriculture Organization of the United Nations Guidelines on food fortification with micronutrients. 2006 ited on 2011 Oct 30 Food manufacturers and governments have used these practices since the 1920s to help prevent nutrient deficiencies in populations.
